I have loved all types of TMNTs! (maybe a bit disliked TMNT 1 a bit only).
There were some weird things in TMNT 4 tournament: If you play the game too much continuously, some special moves became bugged, like Leonardo's revolving kick would finish 2 laps in the entire ground instead of just like 1/3 of it. Donatello would be able to beat Raphael's flying while ascending, but not while descending or swifting in his special move. Raphael himself was objectively too stronger compared to other turtles, like a simple flying kick from him would crack the walls in the first hit, and rarely one character might go completely invisible.
TMNT 3 was my favourite, but I could not pass the spiked turtle shield boss on a skyscraper, I still sort of remember it xD
and omg GTA Vice City! Drone task was awful for beginners, and there were all kinds of myths about collecting all 100 secret packages, and 80 % of the time we were just cheating and bazookaing tanks rather than playing the game

While there were some weird boring parts and looked worse than GTA 3 Liberty City, there were weird details, like honking horn to a girl and he would restore your health in your car. There were also some mods that you could swim in water.
